Description

Technical Field

[0001] The present application relates to the field of valve technology, and in particular to a one-way valve that can be opened electrically. Background Art

[0002] A one-way valve, also known as a check valve or non-return valve, is a fitting used in pipelines to achieve a one-way shut-off function for the medium. It enables the medium to flow in one direction in the pipeline without backflow. For example, a one-way valve is used in a hydraulic system to prevent the reverse flow of oil; a one-way valve is used in a pneumatic system to prevent the reverse flow of compressed air.

[0003] Traditional one-way valves use springs to drive the valve core to achieve control of the flow direction of the medium and one-way sealing. However, installing a spring in a one-way valve will increase the design length of the one-way valve, thereby increasing the weight of the one-way valve. During long-term storage, the spring in the one-way valve is prone to elastic failure, spring solidification after rust, and spring displacement leading to spring failure, which in turn leads to adverse risks such as one-way valve malfunction, failure to open, loose closure, or inability to close. During use, the spring in the one-way valve will increase the gas-liquid flow resistance and easily absorb impurities in the fluid medium, causing the one-way valve to become stuck and fail, or fail to open; the spring in the one-way valve is also prone to failure or reduced elasticity due to frequent vibrations during operation.

[0004] In addition, when using a conventional one-way valve in ground equipment, it is not possible to electrically open or close the conventional one-way valve, and it is not possible to discharge the medium (eg, gas or liquid) downstream of the conventional one-way valve.

[0005] Therefore, it is necessary to propose a new one-way valve that can be opened electrically to solve the problems of traditional one-way valves. Summary of the Invention
